Reviews with images
Accurate easy readings and great customer service.
The meter does exactly what it’s supposed to. And a value at $40+/-My first one arrived and upon inserting the batteries a connector tab broke off. I made arrangements on Amazon for a replacement. Before I even heard from Amazon BTMeter contacted me offering a free replacement. Wow! They communicated with me on 2 other occasions as well to get me a new meter. I was so impressed I actually declined their offer wishing to purchase the meter as originally intended. Great customer service from BTMeter!Shine on! ⚡️🌻💥 🌞

Color: BT881D (0.01~400,000 Lux)Verified Purchase
At noon in full sunlight at 6000 feet in New Mexico, when held normal to the sun, it measures 104,200 lux, which is accurate. The temperature sensor is a few degrees off though. When you turn it off and back on, it does not remember which temperature unit it was last set to and defaults to Celsius. All of the other functions seem to work well. It can also be zeroed out for more accurate low light measurements.
